METHOD OF MODIFYING THERMAL AND ELECTRICAL PROPERTIES OF MULTI-COMPONENT TITANIUM ALLOY

摘要

PROBLEM TO BE SOLVED: To increase the thermal conductivity and the electrical conductivity of a titanium alloy without adversely affecting mechanical property of the titanium alloy.;SOLUTION: A method includes a step of introducing 0.01-18.4% boron into a titanium alloy to produce TiB precipitates and then aligning the TiB precipitates in a direction of metal flow by hot metalworking to obtain a titanium alloy with increased thermal conductivity and electrical conductivity. The step includes: crushing molten titanium alloy containing boron by inert gas to produce an alloy powder containing acicular TiB precipitates; consolidating the alloy powder by HIP treatment; and performing the hot metalworking such as hot forging or hot extrusion.;COPYRIGHT: (C)2012,JPO&INPIT
